BRAKE MEcnenrsM.

Application filed July 3,

provision of new and improved hand operated mechanism for railway brakes together with means for mounting the same on railway cars in such a manner that the same, extends a minimum distance below the frame thereof.

Another object of the invention is the provision of a new and improved brake oper-,

ating mechanism that is cheap to manufacture, easily assembled, efl cient in operation, Wll-l require a minimum amount of space for its operation, that is rugged andsimple in construction, and thatis not likely to be come deranged, broken or out of order.

Other and further objects and advantages of the invention will appear from the followingdescription taken in connection with the accompanying drawings, in which Fig.1 is a side elevation of a portion of a railway car showing the invention in position thereon, with parts broken away; I

Fig. 2 is a diagrammatic view showing the same construction as that shown in Fig. 1, with conventional brakes;

- Fig. 3 is a top plan view of the reversible lever and means for supporting the same; and

Fig. i is a section on line 4 -4 of Fig. 3.

7 On the drawings, the reference character 10designates a railway car comprising the supporting wheels 11 on whichis mounted the underframing of the car, as is usual in such constructions. The underframing includes the longitudinally extending sills 12 and the transversely extending frame members 13 and 14 which may be of channel iron or of any other suitable construction,

The brakes and; brake ope-rating mechanism of one of the trucks are diagrammatically shown at 15 in Fig. 2, and comprise the brake cylinder 16, brake lever 17, and suitable connecting mechanism, all of which may be of the usual or any approved construction. 1

ually operating the brakes independently of the power operated mechanism. As shown,.

an eXpa-nsible and contractable connection between a brake staii 18 mounted ontlie end of the car, and the brake lever 17 is em: ployed for this purpose. comprises a reversiblelever 21 having a lon arm 22 provided with an eat-endedf'curve: winding'surface 23 and a short arm 24; about which is trained a brake cable 25 one end of which is suitably anchored as at 26 andthe other end of which is operatively connected tothe spiral brake druin27 on the brake staff 18. The reversible'lever 21 be of any approved construction, that shown-be; lng substantially like that disclosed in patent to Camp and Bartsch, No.-1,54;3,%i7,Q, June 23, 1925, and need not be fi' rther (16. scribed. r i 1 In order to prevent undue sagging of the brake cable 25, a brake rod 2 8 may be em ,ployed, one end of which is connected to the;

' his nne tion 7 cable 25 andthe other end of which is connected to the cable .or chain 30.-which in turn is secured to; the winding drum 27., The rod is slidably mounted in suitable guides 31 beneath the car. The cable is connected to the reversible lever as at 32. i

In certain types of cars there is not. suflicient room beneath the same to mount the though not necessarily provided with a bot.-

tom plate 35 the outer end of which is curved downwardly as at 36 for guiding the chain 25, during, the Operation of thedevice, and a top member 37 between which the 1'61 versible lever 21 is pivotally mounted to swing about the vertical pivot 38. The inner end of the jaw member 3.4 is pivotally" s5 reversible lever 21 so that it may swing in a r connected to. thebrake lever 17 by the on nector member 39;, which. is preferably though not necessarily flexible.

lVhile the jaw member 3a is disclosed as being provided with a bottom plate having a curved upstanding flange about all except one side of the same, together with a more or less skeleton top member, it is understood that any suitable form of jaw'membermay be employed. The form disclosed is, how ever, ipreferredyb'ecause it protects the parts like causedby the rapidly moving vehicle from below from dirt, gravel, sand and the overth e same, and at the-same time is not unnecessarily heavy and, cumbersome Suitable means are provided for mfo-vably supporting; thej aw member beneath the car.
